Alternatively, you can run the import CLI tool by running `npm install`, then:
82+
83+
```
84+
./import.js path/to/n3/file(s)
85+
```
86+
87+
with the following optional flags:
88+
89+
`-o` or `--output` followed by the desired DB path. If not specified, path will be at `./db`.
90+
91+
`-q` or `--quiet` will silence status updates during the import process. Otherwise, progress information is displayed.
92+
93+
File extensions must be `.n3` or `.nt`. Additionally, there is glob support, so for example `*.nt` will import all the matching n-triple files.
